Zinfandel grapes are ubiquitous in California and its wine quality could be negatively impacted from wildfire smoke. Thus, the occurrence of fires prior to grape harvest presents a persistent problem to both viticulture and enology processes. This is the first broad study on Zinfandel to investigate wine quality defects produced by natural wildfires.

Herein, we report on naturally derived microtubule stabilizers with activity against triple negative breast cancer (TNBC) cell lines, including paclitaxel, fijianolide B/laulimalide (), fijianolide B di-acetate (), and two new semisynthetic analogs of , which include fijianolide J () and fijianolide L (). Similar to paclitaxel, compound demonstrated classic microtubule stabilizing activity with potent (GI = 0.7-17 nM) antiproliferative efficacy among the five molecularly distinct TNBC cell lines.

Forest fires produce malodorous phenols, bioaccumulated in grapes as odorless phenol glycosides (mono- to tri-), and produce unpleasant wines when these complexes are transformed by glycosidases in saliva. Metabolomic analyses were used to further understand by quantitating marker phenolic diglycosides via UHPLC separations and MS/MS multiple reaction monitoring. A collection of grapes and wines provided data to forecast wine quality of grapes subjected to wildfire smoke infestations; the analytics used a panel of reference compounds (-).

The binary hydride, diisobutylaluminum borohydride [(Bu)AlBH], synthesized from diisobutylaluminum hydride (DIBAL) and borane dimethyl sulfide (BMS) has shown great potential in reducing a variety of organic functional groups. This unique binary hydride, (Bu)AlBH, is readily synthesized, versatile, and simple to use. Aldehydes, ketones, esters, and epoxides are reduced very fast to the corresponding alcohols in essentially quantitative yields.
